Righto. I’m going to give this a go on my 81 Volvo B23e. Going to make my Grandad proud.

Your videos make me feel like I should grab my spare metering head and start fiddling with it...

Not sure why in all my research into K-Jet I've never stumbled across your content. It is excellent, really informative and helps to validate all the reading I've done. I've rebuilt the metering head and WUR (16v variety) on my Mk1, and got it running pretty well. When you are doing your volume tests, are you running your rig with a 'warm' WUR, and what position do you have the air metering plate? Haynes manual for the Mk1 doesn't give per injector volume figures, just says to run until you get 100ml and the others should be within a certain % tolerance. Do you know if there are specified per minute volumes published for the Mk1? Sorry, few questions in there! Keep up the great work.

Hi, I use a power supply to simulate a warm environment. Minimum fuel is 120cc/min per injector with the plate lifted 25mm from rest and 20cc/min with the plate at 2mm lift Ideally you want zero imbalance across the number of injectors

Do you soda blast the iron fuel distributors to clean the rust off the outside?

Really useful video, thanks! Curious as to what you use instead of fuel? Last video you said it helps clean and isnt flammable

Hi would the shim modification work on a mk1 golf gti ? And do you need fuel pressure gauge, (havent got one to see p.s I) and how many shims would you recommend without using fuel gauge ,is it best to a pressure gauge? And also would the W.U.R modification work looks slighty different , awesome videos thanks for any help 👍

@GreyGooseRestorations Ай бұрын

You ideally need a set of pressure guages to see whats its going first before upping the pressure. The WUR modification in principle is the same with lowering the control pressure

You have really helped me understand how my KR works. I’d still worry about splitting that metering head though! By increasing fueling as you do is MPG dramatically reduced?

@GreyGooseRestorations 9 ай бұрын

Thanks, not much to be honest, obviously full throttle applications will use more but if all else is well and set to optimum for the engine you won't notice much

whats different beetwen KR/9A engines

@GreyGooseRestorations 9 ай бұрын

KR is 1781cc (1.8ltr) and the 9a is a 1984cc (2.0ltr)

Hello! could you tell me an approximate value of the amount of fuel for a Kr engine? for example, how many deciliters should there be in 1 minute at full throttle?

@GreyGooseRestorations 8 ай бұрын

Book figures state 120 cc/min (1.2 deciliters) when rebuilding and flow testing metering head for 16v KR i set them at 140 cc/min (1.4 deciliters)
