Thanks. I have not yet touched the timing. I was just curious to what it was set at. As for the sticker, I already looked there. This is not the original hood (blue hood, red car) The sticker is for a Suzuki of unknown vintage. Do I need to block the vacuum lines if I just want to look at the timing settings? |

Yes, sir. There's also a centrifugal advance in your distributor. The idle needs to be right, otherwise your timing will be advanced. I have a hood sticker on my '90 that's from a '91. Same systems, so it should be the same for your '89. ![]()

OK! THAT changes everything! Thanks GG! I Plugged both vaccum lines to the distributor (with my fingers) and ran the timing light. Now it's somewhere between 12 and 13 .......... V 20 . . . . . 10 . . . . . 0 Does that mean I have room to advance it a bit more? Edited by BillHoo, Sep 27 2013, 02:15 PM.

You've got it. Back the timing off to 6, and the idle will drop a little bit. |

i once had a 1978 honda civic with the cvcc engine. it was soposed to get 43mpg......it got 18. it burned 2 quarts per tank and smoked like crazy. the choke had to be 3/4 closed in order for the car to be driveable. california made a new law that year, if a older car failed the smog test, they took the car and gave you $500. so i went in for a smog test. every time they changed rpm a cloud of black would leave the tail pipe...then return to white. as luck would have it...... it passed. it didnt just pass, they said its exhaust was so freaking clean it competed with brand new cars of the day (2001) i had to keep the car. one day the dash caught fire. it was awesome, i could control the flames with the dimmer switch. |

OK. So I'll fill it with REGULAR gas. Drive it hard and fast for 30 minutes and time it so that I get to the station as the next customer. Been scoping the testing station and find at 1:30 each day there is one car in line. Before I get tested, I'll bring my timing light and tools and retard the timing down to 6? Or do I need to drive it hard at that setting? |

You might want to get everything set the way you want it before you arrive at the inspection station, just in case you run into a snag. |

Retarding the timing will exacerbate your problem. |

From my perspective I see two options 1. Just wait until January and tell uncle sam to bite you, vintage plates baybay! 2. Get rid of the awful decrepit thing, if you put tons of money into it and it still sucks...it may be time for the car to meet its maker. No geo is worth that amount of goose chasing But that's just me

So here are some numbers to play with. http://www.crypton.co.za/Tto%20know/Emissions/exhaust%20emissions.html "1.0% partially burned fuel produces 200 ppm HC, 10%=2000 ppm HC, 0.1%=20 ppm HC )" 20 ppm is .1 percent of a 10 gallon tank or .001 x 10 = .01 gallons A gallon is 128 ounces .01 x 128 oz = 1.28 ounces per gallon that needs to be displaced to make up for that 20 ppm. So for a 10 gallon tank, I need to displace 12.8 ounces. Isopropyl alcohol is known to burn cleaner, hotter and help reduce HC. Some folks use HEET gas line dryer to reduce emissions. It happens to come in 12 oz. bottles. So if I have less than a half tank of gas (about 4 gallons) and drop in a 12 oz bottle of HEET, my HC emissions should theoreticallyb be in the 255 range. This would be without doing any further engine tuning. |

Drop in about 4 gallons of E85. |

Georgetown Sunoco in DC has E85. That's about 13 miles away. I might check it out. |

![]() ![]() E85 is 105 Octone (RON+MON/2), but it burns more completely and more quickly than the usual hydrocarbon soup known as gasoline. My 50/50 87 octane and E85 recipe is 53.5% E85, which results in about a 50% mixture of Ethanol. 5.671 gallons in a 10.6 gallon tank, and fill the rest with Top Tier 87 Octane. Toss in a 10 ounce bottle of Chevron Techron Concentrate for additional cleaning. You'll feel the kick. |
