My Seloc manual on "Belt timing" seems to differ w/ reference marks on my engine. can anyone tell me exactly which marks on the flywheel... i have three dots on the flywheel and a " ***" on the dist. pulley and a "***' on the dist. base... is this the correct marks to line up. At 800 rpm my timing light shows about 10 degrees ATDC and increasing engine rpm I can't even get to the 5-7 degrees BTDC like the manual asks for
