Hi guys, new to forum, have an older 250z quadsport, owned since new. Been in storage for probably 10 yrs. was stored dry, but don’t think it was running when put away. Son had it. Put battery in it and rebuilt carb, wont start. Has compression and spark, valves have clearance. Will start and run on brake kleen. Assumed carb was bad and replace with cheap Chinese replacement. Same thing. Checked for vacuum leak at carb boot, no leak. Its got me stumped. Would say it skipped cam timeing except it runs on brake kleen. Compression cold was 160 lbs. ordering manual. Any help will be appreciated.
