[QUOTE="gagvanman, post: 626924, member: 17411"] Finished the build of my new 1776 last week. specs: Case - autolinea 90.5 full flowed Crankshaft - Counterweighted 69 Camshaft - Scat C35 Barrels & pistons - 90.5 AA Cylinder Head - 40 x 35.5mm 90.5 CB Performance 26mm Oil Pump Scat lifters Solid rocker shafts Rocker geometry set with 60" shims and longer push rods Twin ICT carbs Huco fuel pump, relay and inertia switch fitted. Put it all together, ran like a dream set the timing and balanced the carbs. Broke in the camshaft Took it for a gentle run only to find a massive oil leak. Engine out, found I had pinched one of the oil cooler seals. New seals and oil change as the cam break in done. All back together and in the van, running like a pig only on no's 1 & 2 cylinders. Checked spark at 3 & 4 ok. Found fuel leaking from the pump. Found I had pinched the O ring when re-orienting the outlet pipe (seems like a recurring theme here) New O ring fitted, still running on 2 cyl. Took carb out and found crud in it. How that happened I do not know, filter on outlet of tank and internal filter in carb. Carb cleaned and blown out. All back together and now running sweet as a nut. Just got to break it in gently and oil change at 1000 miles. Got to love these beasts, otherwise I would have had an epi... [/QUOTE]
