i want to check out and tune up my motor, i don't want to run all over town looking for what i need. anybody have good recommendation for where to buy? have all the chain auto parts stores around here, as well as boater's world and west marine. something inexpensive would be good. i don't want to spend too much money on a tool i will only use a few times.<br /><br />also.. i have read the posts about how to test compression but i wonder what is the best way to ground spark plug wires to prevent damaging the ignition? thanks<br /><br />matt
