Answer
Hi Andy:

Hows it Been? Good I Hope. Just because the Point Set is New Doesn't mean the Condensor is Good. I was Overjoyed when the Nova Ignition Module was Marketed. I have Replaced as Many as 4 Sets Of Points on the Same Mower in a 6 Week Period. Also Check the Compression when the Engine is Hot. A Ring May be Stuck or the Valves May need to be Adjusted. Change the Gearcase Oil. If it is a Heavy Oil, then it Uses 80W90 Gear Lube. If it is Thin Like Oil, then it Uses SAE30 Engine Oil. Another Way to Tell is, if the Case is Cast Iron it Uses 80W90 Gear Lube. If the Case is Aluminum it Uses SAE30 Engine Oil. Now for the Leakdown Tester. I Replaced My Old Tester with the One from Jacks Small Engines. I have Been Using it for a Year and it Works as Good as the Snap-On One I Wore Out. LOL. It was Old too. 20 years or Older. LOL. Tell Mom I said Hello.  Not a Long Question Really. I Love Hearing from Regulars. It Kinda Breaks up the Bordom and Makes it Enjoyable. Be Safe. May the All Mighty Bless You and Yours. Hope this Helps. I am Here if You Require More Assistance. Let Me Know What Happens, Please. Thanks.

Good Luck
