Hello,
Thanks in advance for any help. On to the issue. Bought 2 theft recovery 2003 GTI's. Put a top end on one and it runs perfect. The second GTI new top end .5 mm over, new sbt crank and rotary plate. Basically Its pretty much a new motor. The problem- It runs great on the hose, but refuses to run in the water. Everything I read indicated my rotary clearance was out of spec. Checked it, was out of spec. replaced rotary valve cover with a SBT one. Assumed I was good, went to the lake. Same symptoms will not crank in water. If I pull trailer out of water, crank and tried to slowly go back in water, it dies. So frustrating. Pulled my carb and intake rechecked rotary valve clearance w/o gasket with bend feeler gauge method. It was still out of spec. Reading was .459 mm. So clearance in range is .25 to .35 mm. Is it that strict on the specs and not run at .109 mm out of range? SBT machines the rotary plate cover back to factory spec, Does anyone one know the factory specs on the plate cover for me to check? I looked and double looked in shop manual couldn't find. Sbt tech told me the measurement on the case side is .136 in. on the rotary case lip to plate surface. I haven't checked that yet. Something is putting me out of range. I have done all the standard stuff forum members ask for. Clip plug wires, new plugs gapped to spec. gone through carb 3 times with rebuild kit. pop off in spec, new top end, new sbt crank, all new gaskets, seals. 145 psi's on both pistons. New rotary shaft/gear bought as a kit. new rotary plate, new rotary cover from sbt. Went through all gas hoses and fuel valve selector. Think that's about it. Am I missing something? something else cause my problems?If I can get the measurements on the rotary cover to check it might help. I hope I don't have to disassemble this engine to have the case side machined. I was told it doesn't wear as much as the rotary cover cause of different metal composition.
Any help would be awesome.
