I have just bought a 1968 beetle that has had the engine replaced with a 1600. The engine is slow to start and misfires but I know nothing about engines, can anyone help.
I have already checked; Points - new and clean, Leads - new, clean and connected well, Air filter - clean, Carb - looks ok (but what do I know), Tick over - ok when not misfring, Warm air intake hoses - missing, Distributer - 009 and look new, Fuel plenty and visible in the filter, Airways - clear, Oil - OK.
Tonight I will check the spark plugs but on the basis that the car was serviced not long before I bought it and everything else is new I don't expect this to be a problem.
Please help if you can.

Does it always seem to misfire or just at idle. Does it lack power when driving? don't forget to make sure the plug wires are all on the right plugs. Also check the plugh gaps when you have them out. Also ensure the timing is on the money. make sure there are no intake or exhuast leaks.
Good Luck

If you mean the one hose on each side that delivers air from the fanhousing to the heater system, don't drive without them (or plug off the outlets from the fanhousing) as it will cause overheating.
If this is a dualport engine, they are very susceptible to a hesitation on acceleration if they don't have good intake manifold preheat AND a functional thermostatic air cleaner to deliver warm air to the carb when needed. The 009 distributor aggravates this condition because it doesn't give as much advance off-idle as the stock distributor did. Many will tell you that the 009 has to go, but if you have good preheat & T.A.C. function it should be OK; the timing needs to be set with a strobe light at 30-32° BTDC while the engine speed is above 2500 RPM.
Singleports aren't as fussy since they have smaller manifolds (higher flow velocity=less fuel condensation) but functional preheat and T.A.C. still improve driveability, especially in cool weather.

If the car was just serviced and still does`nt run right then time for a compression check to detect internal problems. Good luck. Bob ingman
