Hey David, I just found your comment! I liked your story, thanks. I still am a big fan of Aermacchis, and I'm taking mine down to the Salt Flats August 22 to see if I can set a record...

Thank you very much. Only just found your comment! I am even healthier than I was 11 months ago..

@@paulbrodie I still watch every video Paul. The speed in which you’ve recovered has been astounding to see

Michael, just found your comments, thank you. I agree with you 100% regarding bike thieves....

Yes, that is exactly how it happened...

Thanks Kevin. Only just found your comments after 11 months... I am even healthier now. And, taking the little Aermacchi down to Bonneville August 22. Hoping to set a Record....

Hello Paul, no worries, have a great day out take care and set a new record! Thanks Kevin.

Thanks for sharing memories. Yes, those were special days; such excitement around motorcycles :)

Sorry to hear you had to part ways. My 350SS is very easy to bump start, which is good, because kickstarting is almost impossible. Aermacchis have their quirks. I only just found your comments, sorry it took 11 months...

Is he British too?

@@paulbrodie hahaha no sir. I’m not sure where he picked it up but my brother and I both say it all the time now.

Thanks 👍 Yes, I jetted it just like the last motor, but I did change the megaphone and had no idea that would make such a huge difference...

Known as the 'Sprint" 250/350 with a high revving engine!

Thanks, but I'm not doing a restoration... I made this bike from scratch.

Me too! Thanks for watching :)

Agree 100%

No worries! Thanks David :)

Thank you Johny. :)

Thanks!!!!!

Well, almost, but we did figure it out for episode 2 :)

Yes 34 or 35 is right. But you do need to start with static timing... we all have to start somewhere..

Thanks Matthew!

Yes too many people ignore the slide cutaway and that can bite you big time, I used to modify the slide cutaway on Aprillia 125's because they were too lean on the slide making them hard to start. Many people just use the idle jet to achieve the same thing and when the slide cutaway is too rich instead of either buying an expensive slide or modifying the cutaway on their existing slide they go to a leaner Pilot Jet and that is when it can bite you big time, Roadracers and Flat track racers are running at high nengine rpm at the end of a straight and when you back off you are running on the Pilot Jet and if you tried a smaller Pilot Jet to cure start richness then the leanness that comes from too small a Pilot Jet can lead to seizure on the overrun in those scenarios.

Thanks for commenting! :)

@@paulbrodie There's another anomaly to check, and that is the exhaust system. I looked to see if you did a "build" video on it. And in this video I couldn't see if the megaphone had a reverse tip or was open. I've come across a few tuning issues directly affected to the exhaust system that are pretty simple to check. What you can do is, take a long 3/8" extension and put the biggest socket you can find on it. When you fire the bike up put the socket up the pipe. What this does is breaks up the reversion back thru the pipe. The reversion charge can flow right thru the combustion chamber during valve overlap and shut off the intake charge at the carburetor. Sometimes if you get spit back the socket will stop it. Spit back usually means lean mixture. But one Harley i worked on and I had black smoke rolling out the exhaust and the thing was spitting back almost every revolution. constantly spit back at idle. I had the richest low speed jet in it. Timing was correct. I took extensions with sockets, ran them up the pipe and the bike idled perfect. A Triumph 750 Bonneville had some kind of "replacement" carbs for the Concentrics (they're effin' crap) Bike had just the header pipes on. No amount of jetting, slides, and needle settings worked. In the end I took a couple of mirror clamping straps, bent them to bolt onto the frame and the other end bent to get into the path of the exhaust, and that disrupted the exhaust flow to stop reversion. I'm thinking I settled at about 1" behind the pipe. So, if everything seems to be set right, the exhaust can be the culprit.

Leeds, York and Hull

Good story, thanks..

Thanks, we did get it mostly figured out..

@@paulbrodie cool, I figured you would. I'll be watching the next video.

I was thinking that if the air intake for the cold start was blanked off, if it was also used for atmospheric pressure for the float chamber would cause issues. But I never really worked with the square bodied Amal, only worked with the Concentric. But if it is the source of atmospheric pressure that would result in a lean condition as that pressure would be missing to "push" the fuel thru the jets.

Thank you kindly
