There's nothing quite like a deadline to actually make things happen. My deadline was the realisation that the MOT was expiring in around 8 days and the car was still in no state to actually go anywhere. What to do?? Easy option was to stall the induction upgrade yet again, rip it all out (again) and put the nikki back on .... or solve a couple of issues.
The upgrade consists of a certain twin SU carb setup that Pete rescued, revived and installed on his car some time ago.
I decided that it would be an interesting alternative to the traditional weber upgrade so a deal was done and a rather large box arrived and took up residence on a shelf. This was end of 2018 if I recall correctly. Then there were questions, a LOT of them, from myself to Pete, back and forth, for a long time. There were little experiments, some worked, most didn't.
Luckily, I share garage space with some clever guys and one is somewhat intrigued by our little rotary engine and was able to come up with some neat solutions. The last update ended with a fuel leak which turned out to be a float bowl o ring. So I got a couple of gasket kits and replaced the o rings in both bowls just to be sure.
Moment of truth ... 3 meters of fuel hose down to the carb on the garage floor. Light blue touch paper and stand back
Not a leak in sight
So the SU's are installed for (hopefully) the final time.
One of the clever mods that my garage mate came up with was modding the OMP linkage. We couldn't use the factory solid link bar so he came up with an ingenious solution combining a motorcycle throttle component, a random Ford part for a mounting bracket and various fittings from a bicycle cable kit.
Still working thru a few little snags and chasing a suspected vacuum leak but it's a worthwhile exercise. And the induction noise is very addictive
I'd probably done no more than 5 miles of testing before presenting TWiR for the annual MOT. I connected up fuel return lines so that they looked as if they were doing something and cobbled together the OMP lines out of some spare stuff that Pete supplied. Got the thing idling on the choke well enough and went thru the exam like a boss
(and then found the idle speed adjusters later that afternoon. Yay for our cars not being subject to an emissions test).
There's always something interesting lurking about at Mullan Speed Shop
So that's MOT for another year. I do have to give a huge shout out to Pete (DKWW2000) for answering all my questions, sending photo's and even CAD drawings on a couple of occasions. For services above and beyond
I got there in the end!
