Larry,<br />Just a thought, I keep thinking timing. Check the manual for the correct timing and see if you are close. Sounds like it may not be advancing as the rpm's jump.

A quick and easy way to check for crankcase leaks is while the engine is running, use a can of WD40 and spray along the gaskets (and bolts etc) if you do have a leak the WD40 will seal it just long enough for the rpms to jump up. Just a thought<br /><br />Happy Boating<br />Link

At long last im sorted.<br />Its always the simple things is'ent it?(embarrising even)<br />After 3 weeks of begging, my mechanic came last night.<br />I was working on this engine in my driveway.<br />Anytime i wanted to rev the engine I just pulled on the lever on the carbs.When you do this it DOES NOT advance the timing.In essence I had already sorted the problem but because of the backfiring I thought I still had a problem.The mixture was not correct on number 1 and 2 cyls and thats why it was weak on those.Many, many thanks to you all and in paticular JIMD who was with me on this one from the start.<br />May all of you stay safe on your boats.You have been great.

Jimd,<br />Apperently when you move the gear lever to go forward it also moves advance timing to coincide with the move up in revs.<br />When I was revving it by hand at the carbs this does not happen, hence the backfiring.<br />Ahh well, I still cant get over the amount of people who wanted to help.<br />Brilliant.<br />Thanks a million.<br />Slán Leat.
