I went up one jet size for my 1679... Id try that with the 1776 too... = especially if your heads arent ported. the 1776's with T3 cooling will = run hot, and lose about 30% of lifespan... but 250 does seem a bit too = hot. Something is wrong... your not using synthetic are you? Ditch the 009... your timing curve is way off with that and may be part = of the problem, you may be running too advanced at one part of the curve = to make up for the retarded curve elsewhere. Keith ' Hi All, I'm trying to find the right main jet size for my new engine (1776, = Berg full-flow, C.W. 69mm crankshaft, stainless steel valves, 009 w/ = Pertronix, dual Solex H32/34 PDS13, currently running 140 main jets) = after my oil temp shot up on the first freeway test drive after only a = few miles (to 250F on my vdo gauge... yikes!). I pulled a spark plug and = it was looking very lean, so considering the fact that everything else = related to cooling is in place (down to the timing hole bung ;) I figure = it must be the air/fuel mixture. Does anyone have a recommendation for = what size jets to try for this configuration? Also, what are the chances a few minutes at this temperature did = serious damage to my new baby?! At around $3K into the job so far I'm = totally paranoid... Thanks!
