940 940 engine swap idle running high?

105Charlie · 06-08-2018, 12:58 PM

Hi guys,

So I've swapped in a B200FT into my 343 and I'm experiencing a very high idle, no exact number as I've got no rev counter but i'd say it's probably 500 over.

I know as standard they run a speedo sensor so I should expect high rev after coming off the throttle but it's even at idle after 20 mins and warm.

It has on occasion dropped down a lot and almost sounded like it was stalling but it was simply because it was actually idling correctly.

Any ideas?

Maybe air leaks or TPS misadjusted.

I thought TPS but that wouldn't explain it dropping to a low idle would it?

Any particular area there could be a leak? Can't see any currently
