HOT START PROCEDURE

[Danb]

I’m having a time with my hot start procedure or lack of. My bravo had no issues with hot starts especially after electronic mag.

Not sure what the Bravo procedure is. On my acclaim I run high boost for a while with the throttle and mixture filly closed then go to the cold start procedure and it will fire right up. Good luck.

As M20TN_Driver suggests, I suspect the best success will come by taking advantage of the TCM "recirculating fuel" system.  With the mixture at idle cutoff, running the boost pump recirculates cool(er) fuel through parts of the system in which the fuel has likely vaporized sitting right above the engine.  At idle cutoff, no fuel is being delivered to the cylinders.  I have read that 30 seconds is not an unreasonable amount of time to run the boost pump at idle cutoff.  At that point, I would be tempted to try a start without priming at all.  If nothing happens in a revolution or two, give it a little bit of prime and try again.  I think it was Mike Busch who said "If it won't start in the summer, you have probably flooded it." and "If it won't start in the winter, you probably need more prime."  Mike flies behind a pair of TSIO-520s with a very similar fuel system.

Contact Brian Kendrick, he has a very fool proof system that has served many well.
